The Jets will look on the opposite sideline Sunday when they face the Raiders and see Tony Sparano, the team’s former offensive coordinator. Sparano was fired following last year, his one season running the Jets offense, after the team finished 30th in total offense.

It turns out it wasn’t all Sparano’s fault.

This year’s Jets are also 30th in total offense and are in the midst of a stretch of bad play that is much worse than any they endured last year. The Jets have gone 114 plays without a touchdown, are the worst passing team in the NFL and are giving up more sacks per pass play than anyone in football. The offense has scored six points in the last two weeks, 20 in the last three.

When it was pointed out the team’s numbers are ugly, wide receiver David Nelson smiled and said, “That’s putting it lightly.”

How much of the blame should fall on Marty Mornhinweg, the man who replaced Sparano as the Jets offensive coordinator? Mornhinweg is Rex Ryan’s third coordinator in three years after the head coach dumped Brian Schottenheimer following the 2011 season and Sparano last year. Through nine games, Mornhinweg was drawing praise and being hailed as one of the team’s most valuable pieces. Over the last three games, his stock has dipped — along with quarterback Geno Smith’s passer rating.But Ryan still gave Mornhinweg a vote of confidence Thursday.

“I think Marty’s done a great job,” Ryan said. “I don’t think there’s any doubt. I think Marty’s doing a terrific job. The numbers can sometimes be a little misleading. I think the job that he’s done and this staff, really, some of the challenges we’ve faced I think guys have done a great job.”

Mornhinweg, who always seems to focus on the positive, said Thursday he feels the offense is closer to clicking than it appears. Last week against the Dolphins, the offense barely functioned. It had two first downs and 39 yards in the first half.
